First Search in Stellar Graveyard Yields Two Possible Planets
Shown here is one of the 20 target white dwarfs of our survey. The white dwarf is at the center of the image and has been masked out. North is up and east is to the left. Nearby to the east is a candidate companion (circled), which if associated would be a massive planet or low mass brown dwarf. It needs further observations to confirm or refute its association with the white dwarf.

Mysterious Cluster of Stars Discovered Near Milky Way
This clump of newly discovered stars in Ursa Major is in a region the size of the full moon centered on Willman 1. To be able to see this ultra-faint object in the SDSS data, the distribution of stars was filtered to enhance its signal relative to the much more numerous closer stars of the Milky Way Galaxy.
